NEWELL V. DYER, OF'HOLBROOK, MASSACHUSETTS, ASSIGNOR TO UNITED SHOEMACHINERY CORPORATION, OF PATTERSON, NEW JERSEY, A CORPORATION OF NEWJERSEY.

MACHINE FOR MARKING MATERIALS.

To all whom it may concern:

Be it known that I, Nnwnrn V. DYER, a citizen of the United States,residing at ldolbrook, in the county of Norfolk and State ofhl'assachusetts, have invented certain, Improvements in Machines forMarking. hflaterials, of which the following description, in connectionwith the accompanying drawings,is a specification, like referencecharacters on the drawings indicating like parts in the several figures'My invention relates to machines for marking various objects, andparticularly to those employed in marking portions of shoes. For suchwork the usual practice is to arrange the stock, when out, with thecorresponding pieces of the right and left shoes of a. pair together;and to identify them unmistakably before they go to the operators forassembling, there are placed upon them symbols indicating, for example,the case number, size, width, and match Ordinarily, these indicationsare applied to the flesh side of one of the pieces of a pair, afterwhich the symbols are similarly placed upon the other piece.

This invention has as an object the provision of a machine wherebydifferent surfaces, as those of pairs of shoe parts, may be marked by asingle operation in an effecti've manner.

A feature of the invention consists in a machine for marking, in whichpieces are placed together and oppositely or simultaneously impressedwith the symbols identifying them. When these pieces are shoe parts, thecorresponding pairs of pieces are laid with their finish surfacestogether, and the impressions made atthe same time upon the oppositesides. p

In thepreferred embodiment the impression members move oppositely toexert independent pressure upon the work. This independence of effect ispreferably obtained by means of separate pressure-receiving memberscooperating with the impression members. To avoid'interference with theplacing of the work between the impression. members, at least one of thepressure-receiving members is movable, so that it may be withdrawn fromthe line in which the work is introduced.

pressions are so arranged upon marking members that one of a pluralitymay be brought into use at a time, as a further feature, the markingmembers bearing these surfaces are so organized that a plurality ofthese members may be selected and then simultaneously acting surfacesbrought into position, the selecting and positioning of the pluralmembers and. surfaces being respectively by a single operation.

These and other features are more fully set forth in the followingdescriptionand illustrated in the accompanying drawings, wherein Figure1 shows. a front elevation of one embodiment of my machine;

Fig. 2 is a side elevation thereof;

Fig. 3 is a longitudinal section illustrating the impression. membersand their supporting and actuating elements, together with a portion ofthe setting mechanism;

Fig. 5 is a broken perspective view of the setting mechanism Fig. 6 is alongitudinal sectional detail through one of the series of impressionmembers; and

Fig. 7 is a detail in side elevation, show ing the parts as; producingtheir impression upon two piecesof material.

A casing 10, in which the operating ele ments of my improved machine aremount-- ed, is provided at its front with recess, at the lower side ofwhich is a horizontal worksupporting surface or table 12. Entrance tothe parts within the. casinguis provided for by removable panel's-14fsituated at the front above and below the tableand' also at the rear ofthe casing. Extending transversely of the casing are horizontal shafts16 and 18, shown as situated just above and below the line of the table,and upon these, shafts are fulcrumed levers 20 and 22, forwardlyextending arms of'which have fixed between them spindles 2 f carryingthe marking members, here shown as consisting of series of adjacent typeor die, disks 26. These disks have extending radially from theirperipheries teeth or projections 28, at the extremities of which aresurfaces for producing the impression upon the work,.these surfacesbeing in the form of any desired symbols, as numbers or letters. Thedisks are mounted to turn upon the spindles and are held at the angle towhich they may be adjusted by retainin members, there being one for eachseries or disks, common to the entire series. Each retaining member mayconsist of a rod 36, located within recess 32 extending along one sideof the s indle and capable of engaging any one 01" series of grooves,semi-circular in cross-section, formed in the openings through the disksabout the spindle. To hold each rod 30 in engagement with the disk'rooves, springs 36 are placed at each extremity, these resting in boxesin the spindle and acting to force the rod outwardly.

To move the levers 20 and 22 and the stamping members carried therebytoward and from the table 12 and a secondary pressure-receiving memberor abutment '38, to be later described, their rear arms have projectionsentering eam-grooves a2 in disks fixed to transverse shaft 44: ournaledin the rear portion of the casing. The projections l0 may be separatelyfixed to the lovers, as by screws. The shaft M has secured upon it agear 46, with which meshes a pinion 48 fast upon a power-shaft 50journaled at the extreme rear of the casing. On this power-shaft arefast and loose pulleys 52, with which may cooperate a belt (no shown)receiving motion "from some suitable source of power. The gear 46 ispreferably joined to the shaft 44 through a. clutch, indicated at 54,this being of any suitable type, preferably adapted to cause a singlerotation of the shaft upon its release by a rod 56 hich may extend to atreadle (not illusted). The cam-grooves -12 are similar in :form but areoppositely placed, being separated by an an e of 180 degrees, and causethe stamping sks to be simultaneously moved toward one another and thecorresponding table or abutment, after which they returned to theirnormal positions. To allow the impression surfaces or dies to make theirimpressions yieldably, the rear arm of each lever 20 and 22 has asection 58. pivoted at 66 upon the main lever and ac"- ing against aspring 62 interposed between the lever and section. in the rearextremities of the sections are the pins 40, and, while theseconstrained to move through vertical paths of unvarying lengths, thedies, by virtue of the springs 62, may yield in accordance with thethickness of work with which they are brought into contact. Firmpressure is thus assured without danger of injury to the work or ofbreaking the marking mechanism.

The vertical alinement of he upper and ower die disks is such, that whenthose car- 'ied by the lever 20 are actin upon work supported on thetable: 12. those mounted upon the lever 22 projects through an open ing6% in the table at the rear of the upper dies and produce theirimpressions against the presstire-receiving member To leave the spaceabove the table 12 clear for the introduction and withdrawal of stock atthe beginning and end or the operation, the member 38 is movably mountedin the cas ing 10, it being illustrated as sliding in inclined ways 66.in the member 38 a rack 7 68 is formed, with which meshes a gear-segment70 at the extremity of an arm 72 ast upon the shaft 16. As lever 20 andits die disks 26 descend to produce their inipression and the lever 22and disks rise, 8 the member 38, through the gearing 68, '70, is moveddown toward the opening 64 to meet the lower impression members 26,forming an abutment which takes the impression upon the lower piece ofstock equal a in efficacy to that furnished by the table for the upperdies. in the opposite or retreating movement of the die disks, themember 38 is withdrawn to a position at which it is clear of the spaceabove the table, so that it does not interfere with the introduction ofthe next piece or" work.

To apply a pigment or marking agent to the dies, pads or other members74: for carrying such agent are supported upon arms 76 9 pivoted upon aslide 78 movable in horizontal ways 80 in the frame. At its rearextremity, the slide has slotted connection with a bell-crank lever 82,fulcrumed in lugs 8d rising from the bottom of the casing. The other armof the lever has a projection 86 extending into a cam-groove 88 in adisk fixed to the cam-shaft a l. As the cam-shaft rotates and the die-lvers are oscillated, the bell-crank lever reciprocates tie slide 7 8from rearward position, at which the pads 74 are clear of the die-disks,forwardly be neath and above said disks, and 'in this movementprojections 90 from rearward extensions of the arms 76 enter oppositegrooves 92, one of which is inclined upwardly and the other downwardlyfrom the horizontal. Under the influence of these grooves, the 76 areswung upon their pivots on the slide, so that, as the pads reach pointsopposite the dies, they are pressed against dies to apply the markingagent thereto. This occurs at the time that the stamping disks are intheir normal position. Thereafter, the slide is moved back and the padswithdrawn to their initial points clear of the paths through which thedie-disks move in the oscillation of the levers.

In the work for which this machine is particularly designed, it iscustomary to impress the same symbols upon two sheets of material aroseid to it. I therefore furnish Fo simultaneously setting thecorresponding upper and lower die-disks, and also for simultaneouslyselecting which pair of disks shall thus be adjusted, by setting meanscommon to the respective series. In their resting positions, the teethof the disks 26 mesh with series oi toothed setting disks 94 mountedbetween cheeks upon the casing on the upper and lower spindles 96, 98,re spectively. These spindles are journaled for rotation and for axialmovement in the opposite walls of the casing, they also sliding throughthe disks 94. The spindle 96 may be turned by a hand Wheel 100 last uponone end, and the spindle 98 is arranged to rotate with it at the samerate by' gearing consisting of sprocket-wheels 102 splined upon thespindles and a chain 10 1 operating over these wheels. In the hubs ofthe sprockets are grooves 193 into which extend projec ions from theframe, iolding them against bodily movement. The chain 104 passesrearwardly from the sprockets 102 over idlers 106 and 108. The former isshown turning upon the shaft 16, while the latter is rotatable upon anarm 110 pivoted upon the side of the casing and urged against the chainby a spring 112 actii to swing the arm to the right, as viewed in 2 ofthe wing, thus keeping the chain properly taut. Projecting radially fromeach of the spindles 96 and 98 is a pin 11 1, which, in the axial.movement of its spindle, may be brought into one of a series of recesses116 arranged in the central opening of each dish about the spindle,there be ing a recess of the series opposite each tooth, and, by thisengagement, the rotation of the spindles may be communicated to thedisks. To simultaneously aline the spindle projections with a particularpair of disks which it may be desired to turn and to confine the settingaction to the pair thus selected, the spindles 96' and 98 each haveconnected to hem by opposite end pieces 118, 118, spindles 120 and 122,all mounted. to reciprocate through openings in the sides of the casingsimilarly to the spindles 96 and 98. The spindles 129 and 122 have teeth124 out on opposite sides to furnish racks, with which mesh pinions 126,126 near the upper and lower extremities of a vertical shaft 1.28journaled in bearings in the top and bottom walls of the casing, andprovided at its upper exremity with a hand-wheel 130 by which it may beturned. On rotating this hand Wheel, the pinions and racks shift theframes "formed by the spindles and side pieces in opposite directions tobring the projections 114. into one or another of the pairs of disks9 1. An index finger 132 is shown as fixed to the upper spindle 122,pointing to the disk which has been selected, that is, into which theprojection 11% has been carried; and to show the operator the symbolswhich are upon the corresponding disks 26, the projections of the disks9 1 have inscribed upon them the respective symbols.

therelations between the elments being such that when a symbol isbeneath the index finger, like symbols are in marking position upon bothof the corresponding disks 26. To look against rotation all the disks 9iex cept the pair at the time in setting engagement with the projections114, the spindles 122 have extended lateral projections 133, which enterbetween the teeth of the disks 94 and hold them 'from turning. Throughthese projections 138, corresponding to the position of the indexfinger, are grooves 134. of such dimensions to permit the rotationthrough each oi them of a single disk. It the operator wishes, forexample, to set the die-disks, the index figure for which appears on thethird. from the left of the upper series oi disks 94 in Fig. 5 of thedrawings, he moves the spindle frames by turning the shaft 128 until theindex finger 132 occupies a position over this third setting disk. Thiswill move the projections 11a of both the spindles 96 and 98 intocorresponding upper and lower die-disks 26, and will look all thesetting wheels 94 except-the selected pair, which are alined with thegrooves 184; in the spindles 122. Then, by means 01 the hand wheel 106and the gearing connecting the spindles 96 and 98, he turns the selectedsetting disks through the engagement of the projections 114 until thecharacter chosen upon the third disk is beneath the index point. Thisindicates that the impression surfaces of both die-disks selected are inthe marking position.

Assuming that my machine is to be used for the purpose of marking partsof shoes upon the flesh side of the leather, the variouscorrespondingpieces of the shoes of a pair are arranged with the grainsides together, and the die disks are set just described to give thedesired case, size, width and match designations. The operator then laysa pair of the pieces upon the table 12, as shown in Fig. 7, and startsthe op'er tion of the machine by engaging the clutch 5 .1. The cammechanism first moves the pads 74"into contact with the lines of chosencharacters upon the die disks, withdraws them, and then moves said disksagainst the work, the member 38. receiving the pressure of the lowerseries of disks, while the upper series acts against the table. This, ata single operation, impresses upon both pieces of thework the sameidentifying designation,

, and. the cam mechanism then withdraws the Having fully described myinvention, what I claim as new and desire to secure by Letters Patentoi" the United States is 1.
